[Qt-interest] Building 64-bit Qt from 32 bit Windows XP

[Dario Ahdoot]

Hi Alex,

I actually tried that. However, I was running into problems. I think the problem I ran into was that the build process built MOC as a 64 bit app. Since I was running a 32 bit OS, the pre-build steps to run MOC failed since it was a 64-bit app. Don't know how you get around this. I guess you can copy the MOC from the 32 bit Qt build into the 64 build and remove the MOC project from the qt build.

During Visual Studio Installation it should created for you something like:
"Visual Studio 2005 x64 Cross Tools Command Prompt" menu.

Run it, it will set environment for crosscompiler (32 bit compiler which produces 64 bit exectuable in this case).

Go to QT folder (from the same command prompt). Follow the same steps when building 32 bit executable.

I am using 64 bit compiler command promt in a similar way, but I believe it should work with crosscompiler. You will not be able to run anything though.
Means you have no way to test, if application even starts.


Best regards.
    Alex

Is it possible to configure and build Qt 64-bit from within 32-bit XP? I'm using Visual Studio 2005.

Thanks in advance,
Dario
